I installed a central vacuum system in the house 25 years ago when we moved in. The motor was to the point it would overheat and the thermal protection circuit breaker would pop after 15 minutes of work.
So out with the old, in the the new. Just snip the zip tie, cut the crimped on factory wire nuts, remove three bolts, and wiggle it out of the enclosure.
The wires are pretty easy to remember, black to black, white to white, and green is ground. It was weird to have a project like this that went smooth and easy. No surprises, no challenges. Usually my projects start with a toilet flap replacement but end up with the total gut and rebuild of the bathroom.
